What is the project about?
The Federal Institute for Material Science and Technology (EMPA) uses – at
its branch in Thun - a device to determine the specific abrasion
properties of two samples rubbing on each other. In the experiments, a
ring and a block are used for this tribometer test. Firstly, the parts are
cleaned, weighted and then installed in the machine. The ring is turned at
a given speed for a given time, while the block is pressed against the
rotating ring. The test chamber can be heated up to 700°C. After the
experiment, the parts are cleaned and weighted again, in order to
determine the mass loss due to friction and consequent abrasion.
In a former diploma project, realized by Martin Stettler of the University
of Applied Science in Burgdorf, an additional device has been developed
and installed. The device allows measuring the friction force as well as
the normal force during an experiment. This enables the user making a
conclusion of the coefficient of friction.
with the new device installed, the oven cannot be heated up anymore.
In this project our task is to expand and modernize the
friction force and the normal force can also be measured in high
temperature experiments. In addition we integrate an automatic control for
the temperature and the rotation speed of the ring-sample.
